Mischa Zverev of Germany celebrates his victory over Kei Nishikori of Japan at the Geneva Open on Friday.

Unseeded Mischa Zverev beat Kei Nishikori 6-4, 3-6, 6-3 to advance to the Geneva Open final on Friday.

The second-seeded Nishikori saved two match points trailing 5—2 on his own serve, but the 33rd-ranked German quickly won his next service game and clinched with a backhand volley winner.
